Anyway, best to think about other things. Such as, for example, the great new NetBeans IDE 5.0 HTML Editor Tutorial. It is not 100% complete, but almost. Here, in an application and tutorial by Jaroslav Tulach, one of the founder members of the NetBeans team, you get to see how easy it is to create an application—without any coding—on top of the NetBeans Platform. (I first mentioned this application in NetBeans is Lego: How to Assemble an HTML Editor.) It is a perfect tutorial for you if the term "NetBeans Platform" is confusing or if you don't really know what you can do with it and how it can help you.
At the end of the tutorial, you learn about something really cool—the shared NetBeans JNLP repository, which ensures that all the applications built on the NetBeans Platform can refer to one repository of NetBeans modules, which means that such modules are shared and do not need to be downloaded more than once.
